We will publish soon an Instructable about how to do it with an Arduino and components that you can buy on Amazon for less than 70$ (the most expensive things are the transducers).
I'm interested in trying this one at home as well. Have you made any progress since you posted this 5 years ago? I see that there were some papers in Japan in 2012. And there are some ultrasonic haptic devices out now-- at least MIT has one that is pretty high res now according to their video.
I haven't tried anything with it, no.
Oops-- guess you posted it even earlier than 5 years ago. Guess you were just still commenting on it 5 years ago.
